PLC Ratio FBT Coupler 80:20 Steel Tube Coupler (Pack of 50 Piece)
This FBT Coupler 80:20 (Pack of 50) delivers precise optical performance across triple wavelengths—1310/1490/1550nm. Its robust 0.9mm steel tube housing ensures stability, while the 1-meter length allows easy integration and supports a long service life.
With an 80:20 split ratio, low insertion loss (≤1.07dB on the 80% output), and low PDL, it’s ideal for telecom engineers working on FTTH, EPON, GPON, or CATV projects. Each unit comes without connectors for flexible splicing and custom fiber assembly.
